I herald the darkness which descends on all creatures;
You will know my approach by moans and wracked features.
I visit the hippo, hyena, and horse,
But never go near snails and spiders, of course.
I would circle the glove, leaping one to the other,
Should all the world's people ever clasp hands together.
What am I?
There is a certain family with both girl and boy children. Each of the boys has the same number of brothers as he has sisters. Each of the girls has twice as many brothers as she has sisters. How many boys and girls are there in this family?
Grandma has an old-fashioned refrigerator with a very small freezer compartment which can hold up to seven ice cube trays stacked, but there are no shelves to separate the trays. You have fifteen trays, each of which can make a dozen cubes, but if you stand one tray on top of another before it's frozen, it will sink into the lower tray and you won't get full cubes from the lower tray. Without using anything but water and the ice cube trays, what is the fastest way to make full ice cubes in seven trays?
If you divide thirty by 1/2 and add 10 what would you have?
They can trickle down,
They can tickle too.
Or make you sneeze,
Or comfort you.
Their rustling sound,
you've rarely heard,
Unless you're a pillow
or a bird!
What are they?
